307 Users of this library are asked to migrate to libswresample, which, as well as
308 providing more functionality, is faster and has higher accuracy.

456 The cuvid decoders now support AVCodecContext.hw_device_ctx, which removes
457 the requirement to set an incomplete AVCodecContext.hw_frames_ctx only to
458 set the Cuda device handle.
460 2017-04-11 - 8378466507 - lavu 55.61.100 - avstring.h

484 Deprecate that demuxers export the stream rotation angle in AVStream.metadata
485 (via an entry named "rotate"). Use av_stream_get_side_data() with
486 AV_PKT_DATA_DISPLAYMATRIX instead, and read the rotation angle with
487 av_display_rotation_get(). The same is done for muxing. Instead of adding a
488 "rotate" entry to AVStream.metadata, AV_PKT_DATA_DISPLAYMATRIX side data has
489 to be added to the AVStream.

524 2017-03-02 - ade7c1a232 - lavc 57.81.104 - videotoolbox.h
525 AVVideotoolboxContext.cv_pix_fmt_type can now be set to 0 to output the
526 native decoder format. (The default value is not changed.)
528 2017-03-02 - 554bc4eea8 - lavu 55.47.101, lavc 57.81.102, lavf 57.66.103
529 Remove requirement to use AVOption or accessors to access certain fields
530 in AVFrame, AVCodecContext, and AVFormatContext that were previously
531 documented as "no direct access" allowed.

549 Deprecate struct vaapi_context and the vaapi.h installed header.

594 Decoders now export the frame timestamp as AVFrame.pts. It was
595 previously exported as AVFrame.pkt_pts, which is now deprecated.
597 Note: When decoding, AVFrame.pts uses the stream/packet timebase,
598 and not the codec timebase.

648 Fix accidental ABI breakage in AVFilterContext.
649 ABI was broken in 8688d3a, lavfi 6.42.100 and released as ffmpeg 3.1.
651 Because of this, ffmpeg and ffplay built against lavfi>=6.42.100 will not be
652 compatible with lavfi>=6.47.100. Potentially also affects other users of
653 libavfilter if they are using one of the affected fields.

719 "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
720 the reset of the ASS ReadOrder field on flush. This affects the content of

724 2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
725 Add a "sub_text_format" subtitles decoding option allowing the values "ass"
726 (recommended) and "ass_with_timings" (not recommended, deprecated, default).
727 The default value for this option will change to "ass" at the next major
728 libavcodec version bump.
730 The current default is "ass_with_timings" for compatibility. This means that
731 all subtitles text decoders currently still output ASS with timings printed
732 as strings in the AVSubtitles.rects[N]->ass fields.
734 Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
735 timing is limited to a 1/100 time base, so this is relevant for any subtitles
736 format needing a bigger one), ease timing adjustments, and prevents the need
737 of removing the timing from the decoded string yourself. This form is also
738 known as "the Matroska form". The timing information (start time, duration)
739 can be found in the AVSubtitles fields.

3141 2009-11-25 - 1433c4a - lavfi 1.10.0 - avfilter_next()
3142 Introduce the avfilter_next() function.
3144 2009-11-25 - 86a60fa - lavfi 1.9.0 - avfilter_register()
3145 Change the signature of avfilter_register() to make it return an
3146 int. This is required since now the registration operation may fail.
3148 2009-11-25 - 74a0059 - lavu 50.5.0 - pixdesc.h API
3149 Make the pixdesc.h API public.

3173 2009-06-19 - a4276ba - lavc 52.32.0 - AVSubtitle.pts
3174 Add a pts field to AVSubtitle which gives the subtitle packet pts
3175 in AV_TIME_BASE. Some subtitle de-/encoders (e.g. XSUB) will
3176 not work right without this.
3178 2009-06-03 - 8f3f2e0 - lavc 52.30.2 - AV_PKT_FLAG_KEY
3179 PKT_FLAG_KEY has been deprecated and will be dropped at the next
3180 major version. Use AV_PKT_FLAG_KEY instead.
3182 2009-06-01 - f988ce6 - lavc 52.30.0 - av_lockmgr_register()
3183 av_lockmgr_register() can be used to register a callback function
3184 that lavc (and in the future, libraries that depend on lavc) can use
3185 to implement mutexes. The application should provide a callback function
3186 that implements the AV_LOCK_* operations described in avcodec.h.
3187 When the lock manager is registered, FFmpeg is guaranteed to behave
3188 correctly in a multi-threaded application.
3190 2009-04-30 - ce1d9c8 - lavc 52.28.0 - av_free_packet()
3191 av_free_packet() is no longer an inline function. It is now exported.
3193 2009-04-11 - 80d403f - lavc 52.25.0 - deprecate av_destruct_packet_nofree()
3194 Please use NULL instead. This has been supported since r16506
3195 (lavf > 52.23.1, lavc > 52.10.0).
3197 2009-04-07 - 7a00bba - lavc 52.23.0 - avcodec_decode_video/audio/subtitle
3198 The old decoding functions are deprecated, all new code should use the
3199 new functions avcodec_decode_video2(), avcodec_decode_audio3() and
3200 avcodec_decode_subtitle2(). These new functions take an AVPacket *pkt
3201 argument instead of a const uint8_t *buf / int buf_size pair.
3203 2009-04-03 - 7b09db3 - lavu 50.3.0 - av_fifo_space()
3204 Introduce the av_fifo_space() function.
3206 2009-04-02 - fabd246 - lavc 52.23.0 - AVPacket
3207 Move AVPacket declaration from libavformat/avformat.h to
3208 libavcodec/avcodec.h.
3210 2009-03-22 - 6e08ca9 - lavu 50.2.0 - RGB32 pixel formats
3211 Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
3212 PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
3213 Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
3214 PIX_FMT_BGR32_1 are now macros.
3215 avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
3216 Re-sort the enum PixelFormat list accordingly.
3217 This change breaks API/ABI backward compatibility.
3219 2009-03-22 - f82674e - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants
3220 Add the enum PixelFormat values:
3221 PIX_FMT_RGB565BE, PIX_FMT_RGB565LE, PIX_FMT_RGB555BE, PIX_FMT_RGB555LE,
3222 PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
3224 2009-03-21 - ee6624e - lavu 50.0.0 - av_random*
3225 The Mersenne Twister PRNG implemented through the av_random* functions
3226 was removed. Use the lagged Fibonacci PRNG through the av_lfg* functions
3229 2009-03-08 - 41dd680 - lavu 50.0.0 - AVFifoBuffer
3230 av_fifo_init, av_fifo_read, av_fifo_write and av_fifo_realloc were dropped
3231 and replaced by av_fifo_alloc, av_fifo_generic_read, av_fifo_generic_write
3232 and av_fifo_realloc2.
3233 In addition, the order of the function arguments of av_fifo_generic_read
3234 was changed to match av_fifo_generic_write.
3235 The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
3236 applications, they may not use sizeof() or directly access members.
3238 2009-03-01 - ec26457 - lavf 52.31.0 - Generic metadata API
3239 Introduce a new metadata API (see av_metadata_get() and friends).
3240 The old API is now deprecated and should not be used anymore. This especially
3241 includes the following structure fields:
3242 - AVFormatContext.title
3243 - AVFormatContext.author
3244 - AVFormatContext.copyright
3245 - AVFormatContext.comment
3246 - AVFormatContext.album
3247 - AVFormatContext.year
3248 - AVFormatContext.track
3249 - AVFormatContext.genre
3252 - AVProgram.provider_name
